No. The coop comes by itself, and, after a couple of expansions, will become home to 60 chickens. You get chickens through eggs, or through neighbors giving them to you.
You cannot harvest your neighbour's crops in FarmVille. You can, however, fertilise their crops and feed their chickens during visits to their farm.
They give you chickens. White eggs give white chickens, brown eggs gives brown chickens and so on. Sometimes they turn into other gifts also such as a picnic set.
Go to your neighbours's farm and feed their chickens in the chicken coop.
ask all your friends to send you one as a a gift or sometimes they come in mystery gifts.
The only way to obtain an Elephant through FarmVille, is by gift. You have to have neighbors, or friends who play FarmVille. If you do, they have the ability to gift you them under the 'Free Gifts' tab on the top left of the game. Elephants, among other animals, are not available for purchase. Only cows, sheep, and chickens.
